Major league umpires are in midseason form on opening night—they've missed at least two calls in the Rangers-Astros game in Houston.

To be fair, they've missed one for each team.

In the first, Houston leadoff hitter Jose Altuve appeared to slide safely into second base while trying to advance on a potential wild pitch, only to be called out by second base umpire Andy Fletcher. Video replay showed Altuve's foot was on the bag before the tag.

In the third, Astros center fielder Justin Maxwell was credited with a catch on a line drive by Elvis Andrus. Replay showed that Maxwell, in fact, trapped the ball.

At least the men in blue got it right on Maxwell's drive to left in the fourth. The ball bounced off Minute Maid Park’s out-of-town scoreboard in left field, meaning it was in play, and Maxwell rumbled into third with a two-run triple. Astros manager Bo Porter asked for a video review, which upheld the call.
